Smart radio communication system and method of operating the same

1. A smart radio communication system comprising: a computer system comprising a processor and a memory; an information collection unit operating on the computer system to collect information associated with each of a plurality of radio access technologies (RATs) through a cooperation with the plurality of RATs; a channel allocation unit operating on the computer system to allocate, to a terminal, an optimal channel for each of services, using the collected information; and a communication unit operating on the computer system to transmit and receive information associated with setting or canceling of the allocated optimal channel using a control channel, wherein the control channel is separately provided from a data channel including the allocated optimal channel, wherein the channel allocation unit generates N terminal groups based on a number N of available frequency bands, and allocates a different available frequency band to each of the N terminal groups based on at least one of the velocity and the data transmission rate to thereby change the allocated optimal channel.

2. The smart radio communication system of claim 1 , wherein the channel allocation unit changes the allocated optimal channel based on at least one of a velocity of the terminal receiving a corresponding service, and a data rate requested by the terminal.

3. The smart radio communication system of claim 2 , wherein the channel allocation unit generates M terminal groups based on a number M of layers of a multi-layered cell, and allocates a cell of a different layer to each of the M terminal groups based on at least one of the velocity and the data transmission rate to thereby change the allocated optimal channel.

4. A method of operating a smart radio communication system, the method comprising: collecting information associated with each of a plurality of RATs through a cooperation with the plurality of RATs; allocating, to a terminal, an optimal channel for each of services, using the collected information; transmitting and receiving information associated with setting or canceling of the allocated optimal channel using a control channel, wherein the control channel is separately provided from a data channel including the allocated optimal channel; generating N terminal groups based on a number N of available frequency bands; and allocating a different available frequency band to each of the N terminal groups based on at least one of the velocity and the data transmission rate to thereby change the allocated optimal channel.

5. The method of claim 4 , further comprising: changing the allocated optimal channel based on at least one of a velocity of the terminal receiving a corresponding service, and a data transmission rate requested by the terminal.

6. The method of claim 5 , wherein the changing comprises: generating M terminal groups based on a number M of layers of a cell that is in a multi-layer structure; and allocating a cell of a different layer to each of the M terminal groups based on at least one of the velocity and the data transmission rate to thereby change the allocated optimal channel.

7. A method of operating a smart radio communication system, the method comprising: collecting information associated with each of a plurality of RATs through a cooperation with the plurality of RATs; allocating, to a terminal, an optimal channel for each of services, using the collected information; transmitting and receiving information associated with setting or canceling of the allocated optimal channel using a control channel, wherein the control channel is separately provided from a data channel including the allocated optimal channel; generating N terminal groups based on a number N of available frequency bands; and allocating a high frequency band from any one of the N terminal groups with a low velocity to any one of the N terminal groups with high velocity terminal with high velocity.
